Numerical simulation of free liquid surface sloshing characteristics in liquid chamber

Abstract It is of great significance to study that the liquid chamber of the submarine-borne missile launching power system is adapted to the swinging environment after liquid injection in engineering application. In this paper, the VOF method and k-ε turbulence model are adopted, and the UDF is used to simulate external load. The simulation results show that the model established in this paper can be used to simulate the sloshing characteristics of the free liquid surface in the liquid chamber of the submarine borne missile launching power system; Under the action of a given swinging load, the free liquid surface of the liquid chamber is within the allowable range of the design, and will not cause adverse effects on the liquid chamber or even the whole launching power system of the submarine-borne missile.
